Renewable energies are increasing its importance between the other energetic sources. The main reason is that they constitute a sustainable alternative to fossil and nuclear fuels, which are destroying natural environments and bringing about pollution. The worldwide is aware of this problem, one of the biggest in the world currently, and governments of many countries are focusing their efforts in building modern and innovative infrastructures to produce by them the most of the energy consumption in the near future.

Eolic energy is one of the main energetic sources in producing electricity nowadays. It exists extensive areas full of wind turbines to collect the power of wind and transform it in electric power. Onshore and offshore wind farms can be found all around the world but the reality is that the future biggest projects focus in offshore wind farms because of its less negative impact in the natural environment than land based projects. Based on data, the United Kingdom is the country with the greatest number of turbines and producing capacity, followed by Denmark and Germany.

Hornsea Project One is the largest offshore wind farm to be built in the next few years. It is expected to be producing energy by 2020 and it is going to be built in the United Kingdom after the British Government gave green light to the project last February. This ambitious offshore wind farm will be located 120 kilometers off the East Yorkshire coast in a huge area of approximately 407 square kilometers, have 174 wind turbines and capacity of 1,200 MW, include more than 900 kilometers of cables and provide electricity to power almost one million homes. The clean electricity produced by the wind turbines will be transmitted to shore and then it will feed the national grid. The project will also give employment to 2,000 people during its construction and phase with up to 300 additional jobs supported directly and indirectly.

Although the United Kingdom counts on the 3 biggest offshore wind farms in the world: London Array, Gwynt y Môr and Greater Gabbard, none of them can be compared with Hornsea Project because, according to the Secretary of State for Energy and Climate Change Amber Rudd, this project will mean clean energy for the country, jobs and financial security for working people and their families, and more skills and growth boosting the Northern Powerhouse than ever before. In order to become even bigger the project, the company commissioned of developing the Hornesea Project One has intention to expand it by building Hornesea Two and Hornesea Three, which are waiting for the consent of the authority at the moment.

Onshore wind is an inexpensive source of electricity capable of competing with coal or gas plants what allows many people to use this kind of energy instead of fossil sources, which are highly polluting. However, offshore wind farms still have a cost considerably high because of the huge invest in infrastructure and its maintenance. Despite this fact, the green benefits of Eolic energy become it in the energy of the future.
